There are more than 15,000 described species of moss worldwide. These underappreciated, primitive green plants fill spaces where other plants cannot or will not grow.
Moss thrives in the following conditions or a combination of the following conditions: compacted soil; poor drainage; persistently wet soil; medium to dense shade; low soil fertility; acidic soil. In landscapes where moss is present, the above issues must be addressed to discourage the growth of moss while encouraging the growth of another plant. If the adverse growing conditions cannot be corrected, consider incorporating the moss into your landscape plan as an alternative groundcover. Moss is low maintenance, grows well under most shade-loving shrubs and deciduous trees, and adds visual interest.
